Weekly Data Challenges
What: A morning of practical data analysis and interpretation. Each week we will consider real or realistic data/image tasks, exploring the applied math and computational area that lives between theory and application. This is a chance to get your hands into real data and exercise your creative side. The questions we will explore are rich and open-ended, yet accessible to all. The goal is not to reproduce known work or results. Our goal is exploration.
Who: Everyone is welcome. You may be interested in this opportunity if (a) you long to think creatively in mathematics/engineering applications, (b) you enjoy coding ideas, (c) you want more practical experience connecting theory to the real world or (d) you've got some free time and are curious.
When: Spring Semester 2012
Time: Wednesdays 9:15 to noon-ish (come for all or part!)
Where: Neill 228 (TBD as needed)
Binary Signal Classification
April 18, 2012
We actually worked on this last week. Here is the data and our code. This week I would like to try new approaches since I think we can do much better. Here is one possible idea.

Image Alignment
March 28, 2012
A fun and interesting application which I will describe this Wednesday. (I assumed that the data was proprietary so it is not posted here. Our efforts worked well! Code was submitted to the experimenters for their assessment.)

Get ouside if you can! No WDC this week.
Modeling Agglomeration (continued)
March 7, 2012
I'd like to review the current code and check out some properties of the agglomeration. Here is our most efficient version of the agglomeration code. (updated 5:30pm by Asaki: code with even better performance.)
